means illustrated includes a part 14 which is rounded on its lower side to present a sloping shoulder and an opposite socket-engaging part 15 which, as illustrated, preferably presents an abrupt socket-engaging shout( er. The outer ends of the parts 111 and V15 are preferably rounded or sloped so that a socket. which may he a simple socket or groinmet 16, may be readily slipped on over the hollow body portion T, pressing the resilient portions 14, 15 toward or into the stud body during the engaging operation. The socket or groiiimet 16 may be secured to an i suitable carrying medium typified by the vabric 1T which, as illustrated, represents a portion of' an automobile curtain, having its lower edge at 18. After the groiiin'iet or socket has been completely en gaged with the stud, the parts assume the iosition best shown in Fig. 2. The abrupt shoulder on the part 15 will prevent separation of stud and socket occasioned by any ordinary strain exerted against that portion of the fabric 1T which lies above the stud. )n the other hand, the socket may be readil separated from the stud by an outward )u l on that portion of the curtain or fa ric which lies below the stud, as by a pull on the edge 18. The spring plate 13 may be, as illustrated. round in contour and have struck up from it the parts 14 and 15, as heretofore described. A considerable portion of the resiliency may come from portions of the spring which lie generally in the plane of thev spring plate 13. To permit free lay of the resilient portions i0 and Q1 ofp the spring plate, the stud base 8 is preferably somewhat s aced away from the outer face of the spring plate, while the outer marginal portion of the spring plate and the outer marginal portion of the screw head 11 may be gripped between the stud base flange 10 and the outer marginal portion of the stud base 8. To facilitate screwing of the stud Screw 12 into the carrier 6, the head 11 of the stud is preferably of noncireular shape, as illustrated hexa onal, while the rim 9 may conveniently be s aped to lit the periphery of the stud head, so as to precludeturning of the stud proper relative to its screw and so as to permit easy aplication of a wrench to the rim 9.

While I have shown and described a preferred forni of one embodiment of my invention. it will be understood that changes `from said plate and involving omission, substitution, alteration and reversal of parts` and even rhanges in th(l mode of operation, may be made without departing from the scope of my inven tion, which is best defined in th(l following claims.

(.llaims:

1. A resilient stud for separable fasteners comprising a casing, a spring metal plate in said casing, and a resiliently movable portion integral with and opstanding projecting through said easing.

2. A resilient stud for separable fasteners comprising a casing, a spring metal plate in said easing, and resiliently movable portions integral with and upstanding. from. said plate and projecting through said easing.

3. A resilient stud for separable fasteners comprising a casing, a spring metal plate in said easing, and a resiliently movable portion opstanding from said plate and project ing through said easing, said resilientllv movable portion presenting a rounded shou der exterior to said easing and toward the inner end of said casing.

4. A resilient stud for separable fasteners comprising a easing, in said Casin and resiliently movable portions upstaning from said plate and projecting through said casing, one of said resiliently movable portions presenting a relatively abrupt Shoulder toward the inner end of said casing and the other of said resiliently movable portions presenting a less abrupt shoulder toward the inner end of Said easing.

5. A resilient stud for separable fastena spring metal plate ers comprising a easing having a base, a spring plate having resilient portions beneath said base and resiliently movable jaw means integral with and opstanding from Said base and projecting through said rasing, said stud base spaced away from the` resilient portions of said spring plate.

6. A resilient stud for separable fasteners comprising a casing having a base, a spring plate having resilient portionsl beneath said base and resiliently movable jaw means up standing from said base and projecting through said casing, Said stud base spared away from the resilient portions of said spring plate, and Said stud base gripping the peripheral portions of said spring plate against the head of a Stud-securing screw.

A spring for the resilient stud Yof a separable fastener formed from a single sheet of metaland presenting a spring plate having two opstanding resiliently movable porn tions.

8. A spring for the resilient stud of a sepA arable fastener formed from a single sheet of metal and presenting a spring plate havlng two oppositely disposed npstanding resiliently movable portions.

9. A spring for the resilient stud of a separable fastener formed from sheet of metal and presenting a spring plate having two opstanding resiliently movable portions` said spring plate slotted adjacent the juncture therewith of said opstanding portions to provlde increased resiliency of said npstandlng portions.

In testimony whereof, I have signed my name to this specification.
